Reset temporal denoiser state on significant changes #661

Open w23 opened 6 months ago

w23 commented 6 months ago

Temporal denoiser should be cleared on any spatial discontinuities:

map change
load
teleport
what else?

Mostly affects reproducible rendering regression testing

Still isn't done. All previous attempts failed so far for yet unknown reason. It might be the case that current ad-hoc g-buffer texture tracking is lacking, and a more proper per-object (almost-rendergraph) kind of tracking is needed.
